GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 583,225, dated May 25,1897.

Application filed January 29, 1897. Serial No. 621,229. (No model.)

To all whom it may concern;

Be it known that I, JOHN FRIEDLANDER, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Gas- Burners, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming a part hereof.

My invention has relation to improvements in gas-burners; and itconsists in the novel arrangement and combination of parts more fullyset forth in the specification, and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of my improved burner, andFig. 2 is a detached perspective view of the spider carrying the disk bywhich a conical form is imparted to the otherwise cylindrical flame.

The present invention is a modification of the construction of burnerset forth and described in my pending application for Letters Patent,filed June 6, 1896, Serial No. 594,549, and has for its object tosimplify the mechanism by which the tubular cylindrical flame of theArgand burner, of which the present attachment forms a part, isconverted into a conical or tapering flame, and by which at the sametime a perfect condition of incandescence of the carbon constituting theflame is insured.

In detail the invention may be described as follows:

Referring to the drawings, 1 represents an ordinary base which may besecured to any gas pipe or fixture supplying gas and to which theordinary Argand burner is generally secured, the burner proper, 2, beingprovided, as is well known, with a series of openings 3, arranged in acircle along the upper circular edge of the burner and adapted toproduce a tubular flame substantially cylindrical in form. Adapted to besupported by the upper circular edge of the burner 2 is a spider 4:, thelatter being suspended from said burner by means of aresilient orelastic series of radiatin g arms 5, each having a terminaloutwardly-deflected finger or end 5, resting directly on said uppercircular edge, the resiliency of the arms allowing the latter to readilyconform to any slight inequalities of dimensions of the circle of theedge of said burner,

whereby a tight connection between said'arms and the burner is alwaysinsured. The vertical offset by which each finger is connected to thearm proper bears against the inner periphery of the conical surface ofthe burner adjacent to the upper edge of the latter, so that the spidernot only rests on the upper edge of the burner but is prevented againstlateral displacement by the friction between the said offset and theinner peripheral surface of the burner. The conical form of the Argandburner precludes the possibility of securing the spider in any otherpractical way,

article of manufacture is provided with no means of attaching the spiderwithout necessitating a reconstruction of the burner itself; and when itis recollected that cheapness is a desideratum the present manner ofsecuring the spider is the only practical one. Proeotin g upwardly andvertically from the center of the spider is a stem 6, which extends asuitable distance beyond or above the upper circular edge of the burner,said stem being surmounted by a circular perforated disk 7, said diskserving to impart a tapering or conical form to the flame 8, and theopenings of said disk allowing for the free and uninterrupted passagetherethrough of the air-currents by which the necessary draft to theflame is imparted. The spider thus serves to accurately and properlycenter the disk 7 within the otherwise cylindrical flame, (as producedby the Argand burner,) converting the latter into a tapering form offlame greatly resembling in outline the mantle on the wellknownWVelsbach burner. At the same time the air currents passing through thedisk serve by reason of their velocity through the openings of the diskto furnish and carry to thereby causing the carbon of the flame toassume a perfect condition of incandescence and perfectly whitening theflame.

Having described my invention, what I claim is- 1. As an article ofmanufacture to be used in connection with an Argand burner, a suitablespider having a series of radiating arms, outwardly-deflected portionsor fingers forming the terminals of said arms and adapted to rest on theupper edge of the conical burner,
